Extrusion production adopts on-line cooling, including strong wind cooling, water mist cooling and water-cooling;4)When the profile temperature is below 60ºC,straightening treatment is carried out,and the straightening rate is 0.5 ~1.0%;5)After sawing,the fixed length can be 3000-7000mm;6)After sawing,the product shall be subject to artificial aging heat treatment for 8hours;7)Quality inspection:key dimensions,hardness,mechanical property test and surface quality test,etc;8)Packing and warehousingOur company has many years of experience in producing 6005/6061/6082/7003 aluminum alloy shock absorber profiles,the production have excellent comprehensive performance, the yield strength can be be more than 340Mpa, tensile strength greater than 380Mpa, elongation greater than 10%. Our products are well received by customers, the main customers of our company's automobile aluminum alloy profiles are famous automobile companies such as BMW, Mercedes Benz, etc., We warmly welcome new and old customers to contact us for business!Chizhou Jiuhua Mingkun Aluminum CO.;LTDWELCOME TO ConTACT USContact:William WangWebsite:http://www.mkly-alu.comAddress:No 200 Qingxi Avenue,High-tech development district,Chizhou City,Anhui Province,ChinaPast Code:247000
